Frasch process mining Britannica

2021-8-22  Frasch process, method of mining deep-lying sulfur invented by the German-born American chemist Herman Frasch. The process involves superheating water to about 170 °C (340 °F) and forcing it into the deposit in order to melt the sulfur (melting point of about 115 °C, or 240 °F), which is lifted to the surface by means of compressed air.
